We'll be keeping track of what you can and cannot do with your (probable) snow day.

Museums: open or closed?

Closed: Pretty much everything. The Smithsonian museums, the National Zoo, National Gallery of Art, Library of Congress, National Building Museum, Library of Congress, National Museum of Women in the Arts, Newseum, Phillips Collection, Corcoran, Spy Museum. If something's not listed here, assume it's closed.

Is the play/concert/show I have tickets for still happening?

Not happening: "Mother Courage" and "Tallest Tree in the Forest" at Arena Stage, performances at Studio Theatre, "Constellation Theatre's "Scapin," all performances at the Kennedy Center, movies at AFI's Silver Theatre, Rorschach Theatre's "Glassheart," "Yellow Face" at Theater J, "Seminar" at Round House, matinees at Landmark's E Street Cinema, Christian Finnegan at DC Improv, "How to Succeed in Business Without Really Trying" at Olney Theatre, "Richard III" at Folger Theatre, "Our Funny Valentine" at Signature Theatre, "Disney on Ice" at Verizon Center, "Violet" at Ford's Theatre, anything at Strathmore, Buckwheat Zydeco at Wolf Trap, the Travis Jackson benefit at the Black Cat (a new date will be announced later this week), Yuck at the Rock and Roll Hotel, the Speakeasy Bash at the Woodrow Wilson House.

Woolly Mammoth's 8 p.m. performance of "We Are Proud to Present ..." will proceed as scheduled, but guests may exchange tickets for a different showtime.

More to come.

Okay, now the important stuff. Any food or drink specials I might like?

Yes, but you must promise to tip well. Your server or bartender had to trek in today even if you didn't. Many restaurants -- from Rose's Luxury to Florida Avenue Grill -- are closed today, so if you're thinking about heading out for food, call ahead or check Twitter first.
